Given numbers are 931, 930, 689, 619
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(931, 930) = 865830
GCD(931, 930) = ( 931 x 930 ) / 865830
= 931 / 930
= 931
Step2:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
Step3:
LCM(1, 619) = 619
GCD(1, 619) = ( 1 x 619 ) / 619
= 1 / 619
= 1
So, Greatest Common Divisor of 931, 930, 689, 619 is 1
